CARL AUGUST RGDER, OF SOLINGEN, GERMANY, ASSIGNOR TO HERMAN BOKER & 00., OF NEW YORK, N. Y.

BUTTQN-HOLE CUTTER.

SPECIFICATION forming part of Letters Patent No. 328,813, dated October 20, 1885. Application filed September 3, 1885. Serial No. 176,050. (No model.)

To all whom it may concern:

Be it known that I, CARL ,A. RoDER, of

Solingen, Germany, have invented a new and useful Improvement in Button-Hole Scissors, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved buttonhole scissors, which are so constructed that they can be adjusted very easily for button-holes of a certain size, which adjustment is retained until changed.

The invention consists in the combination, with button hole scissors having notched edges, of a polygonal button pivoted on one blade at the intersection of the blades, as hereinafter fully described, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front view of a pair of scissors of my improved construction closed. Fig. 2 is a front view of the same partly closed.

v Fig. 3 is an enlarged cross-sectional view of the same. Fig. 4 is an enlarged cross-sectional view of a modification of the same.

The scissor-blades A are pivoted together by a screw or pivot, B, and each blade has a handle-hoop, C, and a notch or recess, D, forming the cutting parts E of the blades. The blades cross each other, and each has a diagonal edge, a.

One blade is provided adjacent to the diagonal edge a of the other with a button, F, having a pin, G, mounted to turn in the blade, and a handle-wing, H. The button is eccentric in relation to its pivotthat is, some points of the rim are farther from the pivot than others. The rim is made polygonalthat is, it is composed of a series of small sides at slight angles to each other.

\Vhen the button F has the normal position, its long straight side comes in contact with the edge a of the other blade.

When a button-hole is to be cut, the blades must be adjusted to overlap less, and to accomplish this the button F must be adjusted in different positions, according to the size of the button-hole. When the button F is so adjusted that the edge a of the other blade comes in contact with that edge of the button F farthest from the pivot G of said button, the cutting parts of the blades will overlap less than when the button F is so adjusted that its point which is the shortest distance from the pivot G comes in contact with the edges a.

For intermediate sizes of button-holes, the button F is adjusted so that the edge a comes in contact with one of .the intermediate spaces or sides of the button F.

Inv the construction shown in Fig. 3, the button F turns with its pivot.

In the construction shown in Fig. 4, the pivot G is fixed and the button F turns on said pivot.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combinati0n,with two crossed and pivoted button-hole scissor-blades having diagonal edges a, of the polygonal button F, provided with the handle-wing H, and pivoted eccentrically on one scissor-blade adjacent to the diagonal edge a of the other blade, substantially as and for the purpose set forth.
